What are the symptoms of fever and cramps?

If a child has fever and convulsions at the same time, parents should be alert, because the child may have an intracranial or extracranial disease, or may have suffered a convulsion, so timely medical examination and treatment are required. Fever can cause great damage to children's body cells and needs to be treated promptly and correctly.

What is a fever convulsion

Fever and convulsions are one of the common emergencies in infancy and childhood.

The professional medical name for febrile convulsions is febrile convulsion. Febrile convulsions are mainly caused by the incomplete development of the nervous system of infants and young children. Once stimulated by body heat, the body's excitement stimulates the nervous system and causes convulsions. Generally speaking, fever convulsions often occur in infants and young children between six months and four years old, especially babies who often catch colds and fevers, who are more likely to suffer from high temperature convulsions. Convulsions usually occur when the baby has a high fever, such as a body temperature of 39℃-40℃, and last for a relatively short time, about 2-3 minutes, and generally do not exceed 10 minutes. After the convulsion stopped, the child woke up.

High fever convulsions are one of the more common emergencies in infancy and childhood. Sudden whole-body convulsions or rigid convulsions of localized muscle groups are its obvious characteristics, and most children who become ill are accompanied by symptoms of unconsciousness. The incidence of convulsions in children is 10 times that of adults, especially in infants and young children. High fever convulsions recurred. As children get older, the chance of a second seizure decreases. Children over 6 years old are less likely to have a febrile seizure.

Causes of fever and convulsions

The causes of febrile convulsions can be roughly divided into two categories: intracranial convulsions and extracranial convulsions according to the site of the lesion.

1. Intracranial diseases: viral infections (such as viral encephalitis and Japanese encephalitis), bacterial infections (such as purulent meningitis and tuberculous meningitis), brain abscesses and venous sinus thrombosis, fungal infections (such as cryptococcal meningitis), etc. Parasitic infections such as cerebral cysticercosis, cerebral malaria, cerebral schistosomiasis, cerebral paragonimiasis, and toxoplasmosis.

2. Extracranial diseases: high fever convulsions, toxic encephalopathy (severe pneumonia, whooping cough, toxic dysentery, sepsis as primary diseases), tetanus, etc.
